Okay, I've now managed to figure out what was wrong with the "adapter
not found" error (I had to install ruby-mysql). Now I am getting an
infinte loop:
INFO: Creating database 'blog'.
INFO: Database 'blog' not found!
INFO: Creating database 'blog'.
INFO: Database 'blog' not found!
... and so on.
I tried running this as root in case it was a permissions error.
Suggestions?
